I don't know about illegal....but I'd not be able to rest til I knew what happened!
Our county has several calls a month about 1 car accidents on I-20 close to where I am. Unless it's a rollover or in the median, stuck, 9 times out of 10, it's a reported Unable To Locate. People drive off the road, no damage, and continue on their way. Also, if the 911 caller doesn't know the mile marker....it can be tricky.
The 2003 white Mazda car was found about a half-mile north of U.S. Highway 64 along Interstate 95 in Rocky Mount. According to the North Carolina Highway Patrol, Nash County communications had received a 911 call about an accident in the area about 7:29 a.m. Thursday morning. Emergency responders reported not being able to find any vehicle involved in an accident.
